I put the rear bumper on the Cabrio this morning, and I'm very pleased with the look and quality of the bar itself. The powder-coating was flawless on the bars, but there were a couple of weak spots in the bolt holes that were quickly remedied with a shot of gloss Krylon - I know that's a difficult place to get the finish coat into. I wasn't going to worry about it, given how long I've been waiting to put the car together and how fast Ernie's people got the bumpers to me.
Photos are in my gallery. If it stops raining before I go off vacation, I'll take my Dremel to the left-front cover and cut the hole for mounting the front bumper.
Cheers, BPP!
